Problems solved by technology

Chamomile flower, a spice-type plant, not only contains chamomile flower essential oil, but also contains a large amount of plant waxes, proteins, glycosides, sugars, natural pigments and other components that are extremely beneficial to the human body but are not volatile. Only through traditional distillation Extraction and utilization cannot be realized by the method; (2) CO 2 The extraction rate of chamomile flower extract obtained by supercritical extraction is ≤2.8%
[0003] The invention provides an ultrasonic extraction method, which not only extracts the essential oil of chamomile flowers, but also extracts a large amount of non-volatile plant waxes, proteins, glycosides, sugars, natural pigments and other components (accounting for 20-50% of the total amount of the extract), However, these components with high utilization value cannot be realized through traditional extraction methods.

preparation approach 1

[0021] Take 10kg of roses that have been crushed through a 20-mesh sieve, and put them into a tank-type ultrasound machine that meets the JB / T20126-2009 national standard at a mass ratio of 1:8 with the organic solvent ethanol (95%) produced by Xinjiang Jiepule Biotechnology Co., Ltd. In the extractor, keep the temperature of the ultrasonic extraction tank at 40°C for 35 minutes to obtain the chamomile flower ethanol mixture; enter the mixture into the liquid slag squeeze separation device, separate the slag and the extraction mixture, and input the extraction mixture into the dynamic cycle low temperature decompression (-0.06MPa) in the evaporator concentrator, keep the temperature at 35°C, evaporate and recover the organic solvent ethanol, collect 1.2kg of the extract, which is the chamomile flower extract, and the yield is 12%.

preparation approach 2

[0023] Take 10kg of chamomile flowers that have been crushed through a 40-mesh sieve, and put them in a tank-type ultrasonic extraction machine that meets the JB / T20126-2009 national standard with the organic solvent ethyl acetate produced by Tianjin Fuyu Fine Chemical Co., Ltd. in a mass ratio of 1:10 , keep the temperature of the ultrasonic extraction tank at 45°C and extract for 40 minutes to obtain the chamomile flower ethyl acetate mixture; input the mixture into the liquid slag separation device, separate the slag and the extraction mixture, and input the extraction mixture into the dynamic cycle low temperature decompression (-0.06 MPa) in the evaporation concentrator, keep the temperature at 50°C, evaporate and recover the ethyl acetate, collect 1.0kg of the extract, which is the chamomile flower extract, and the yield is 10%.

[0024] This method obtains the application effect of the extract:

Embodiment 1

[0026] Addition of chamomile handmade soap:

[0027] In the production of handmade soap, after the saponification reaction process is completed, 1.8% (kg / kg) of rose extract is added when the temperature of the saponification solution is kept at 60°C, stirred evenly at a constant temperature, injected into the molding mold, cooled, divided, and packaged to obtain chamomile handmade soap. The chamomile extract is used in the production of handmade soaps, replacing the use of chemical essences and pigments in ordinary soaps. After use, the body surface can retain fragrance continuously, and can play the role of whitening, moisturizing, moisturizing, antibacterial, and anti-allergic. .

Abstract

The invention provides a method for extracting chamomile extract by using a pot-type ultrasonic device. The method comprises the following steps: drying fresh chamomile flower petals in shade, smashing and sieving the chamomile flower petals by using a sieve with 10-40 meshes, mixing the sieved chamomile flower petals with organic solvent according to the mass ratio of the chamomile flower petals to the organic solvent of 1 to (5-10), placing the mixture in the pot-type ultrasonic extraction machine for extraction, performing extraction at the temperature of 25-55 DEG C for 20-60 min to obtain a mixture of the chamomile flower and the organic solvent, placing the mixture in a liquid slag separation device to be subjected to squeezing and separation at the speed of 20-100 kg / h to obtain a mixture of the chamomile flower extract and the organic solvent; placing the mixture into a dynamic circulating low-temperature evaporation concentrator, reducing the pressure to -0.06 MPa, and recycling the organic solvent at the temperature of 20-55 DEG C to obtain the chamomile extract. According to the method, the yield of the chamomile flower extract is larger than or equal to 10 percent.

Description

technical field [0001] The invention relates to a process of chamomile flower extract, especially the extraction by ultrasonic wave. The method has a remarkable effect on improving the extraction rate of effective plant components. Background technique [0002] Traditional chamomile flower extraction methods: (1) Steam distillation to obtain a single chamomile flower essential oil. The main components are volatile aromatic esters, aromatic alcohols, terpenes, and cyclic hydrocarbons. The extraction rate of chamomile flower essential oil is ≤1.5%. Chamomile flower, a spice-type plant, not only contains chamomile flower essential oil, but also contains a large amount of plant waxes, proteins, glycosides, sugars, natural pigments and other ingredients that are extremely beneficial to the human body but are not volatile. Only through traditional distillation Extraction and utilization cannot be realized by the method; (2) CO 2 The extraction rate of the chamomile flower extrac...
